You can set the maximum number of socket connections to the Server on the Site. If you have multiple Sites, you can configure some Sites to allow more users than other Sites.
The Max concurrent socket connections check box limits the amount of socket or low-level connections allowed by the Server. When this limit is reached, any subsequent connection attempt generates a socket or network error in the client. It reacts as if the Server is not available, because EFT Server refuses the connection entirely. For a Server configured as an anonymous FTP server, it is recommended to limit connections per user. In this case, EFT Server will allow the user to partially connect before being told that EFT Server is full or busy, which is a more graceful way of denying the connection.
To restrict the number of socket connections
In the administration interface, connect to EFT Server and click the Server tab.
In the left pane, click the Site you want to configure.
In the right pane, click the Connections tab.
In the Network Usage and Security Settings area, next to Connection limits, click Configure. The Connection Limits dialog box appears.
Select the Max concurrent socket connections check box, then specify the maximum number of users you want to allow at any given time. If the box is cleared, the Server does not restrict the number of users.
Click OK to close the dialog box.
Click Apply to save the changes on EFT Server.
